Dave also asked if there is plan to integrate with existing messaging system, e.g. RabbitMQ. Bryan responded that we don't want to over burning existing messaging system, thus it may not directly plug into messaging app. Dave said that it could be a different (instance) of messaging app. Bryan acknowledged it could be. More importantly, what technology to leverage is subject to discussion.

Maryam Tahhan (Intel) asked if Neutron Instrumentation is considered. Maryam then shared the link, and Bryan agreed to further look into it.

Maryam further asked how scaling is considered. She had a concern of adding another layer of overhead. Bryan answered that we will minimize the connection among VMs. There are 2 types of events to handle. One is machine-generic events, and the other is VNF/app-specific events. Bryan further explained that in ECOMP, there is an event collector (DCAE) sitting directly above infrastructure. There will be plugins for OpenStack so that those data can be consumed by OpenStack. Bryan agreed to add a diagram to further clarify it.

Maryam asked if any open source is considered. Bryan agreed to look into it.

Dave asked because of there are lots of interest here, not onlt VNF, but also infrastructure, data fast path, etc., Dave suggested to discuss use cases etc in mailing list. There is only one committer here. We need to look for more contributors. Bryan agreed.
